An assembly of components designed to enable the creation of sizable timekeeping devices. This includes the gears, pendulum or other regulating element, and face that, when combined, form a functioning, often visually prominent, clock. One example could be a set purchased for building a grand, wall-mounted timepiece intended as a focal point in a living space.
Such a collection allows for customization and personalization of timekeeping instruments beyond commercially available options. Historically, constructing time-telling devices was a skill often associated with precision and craftsmanship, demonstrating an understanding of mechanics and design. The practice provides both a functional object and an artistic expression of individual style and skill.
